The rollers 35? determine ille exnet ninnnnl (rf liiernl nime nienr svliirli muy be inipznl'ed t0 lie refininc-:ilnr-r member Ill. lt will iw understand that tlie erosnllend 341'! is pivored 01.1 :i linli 4l ex Sil tending upwardliY from a slide 42 which moves in the guides '13 in the table 32. Thus the reciprocating carrier 3l is adapted to have a lateral movement depending upon the position of the positioning rollers 33 and the arms 30. and a riafiprocating movement, such reciprocating movement being imparted to it by the following mechanism. The shaft il is provided with a crank 44 to which is connected a link 45. This link is pivotallv con nectcd to a depending arm elfi on a slidi` lift. ruiming backward and torward in guides .461 on the table 32. The slide 46a is adjustablv connected b v a threaded bolt 46c to the elide 16.2. The arm 46 has l'iivotally connected to it another linlt 4T which is lidiar-Tabl)v mounted at its other cud in a cra l( arm i8 pivoted at i9 on the leg 1 and Carries on its pivotal end a cam surtace 50 adapted to engage with a cam roller 5l w ich is pivolalljvv mounted on the end of a slide 52 carried in a guide 53 on the upper end of the leg l. The adjustable end 54 of this slide engages with the under surface ot' the table 32 ifo that the table is moved up and down at its tree end about its pivotal support on the trame. at 55.

The reciprocating carrier 34@ carries an adjustable slotted arm 56 in which is located a screw or bolt 5T that adjusts the position of this arm. This arm carries a heel holder cmnprising a head 58. On either side of the head at 59a are pivotally mounted side members 59 between the free ende` ol which there, is located the longitudinallj adjustable heel retaining block GO which embraces the rear ot the heel while the forward or breast tace oi'V the heel is engaged by an arcuate replaceable men'iber (il carried b v the head Btl. The overhanging arm (52 has an adjustable c Laaging screw G3 depending therefrom, which engages the bottom ot' the heel. as the heel is in up side-down position so that its upirer surface can be concaved or grooved. rElie notched boel retaining block (3U acting upon the tapered peripheryv of the heel serves to press the heel toward the table, and also toward the member (il. This brings me to an imporlant feature of my invention. namely` the use in the table 32 ot' a detachable. removable plate (il which is located in a cut-away portion ot the table. This plato is of soft vond, libre or soft niet-a1 and is adapted to have a portion cut therethrough which is of the same dimensions as the effective crosfesoctiim ol' the milling cutter G5 which is carried ou the shaft 66 that drives it. This plate is retained in position by detachable supports 6'." on the bottom ot" the table In handlingl the removable plate Gl, which may be made ol' any soit material, it is my practice. to insert it in the table 32 allowing it to drop on the cutter which cuts a hole exactly the same size as the cutter. The. cutter adapted to project through the removable piattand slightly above il eo that as the heel is rvciprocated over il it will cut a ,shallow concavity out of the heel. the width ot which is determined bip the lateral position imparted to the heel. As there is a margin around the heel ot nearly one sixteenth of an inch that is not acted on bj; the cutter. this margin is supported by the plate (i4. 'l'lie lateral positioning of the heel is controlled through the cam plate 18 and its associated mechanism 35a, 39 which serves` to shift the arms lll) and the position ot' the guiding rollers il?, which in turn moves the slide 3l about its pivot il and determines the exact direction of its reciprocation. B v adjusting the came mechanism lion, 39 it is possible to var v the width oi' the groove.

The depth oi the cut is determined by the adjustment ot the screw Fri. ,lt a verticallyv sloping cut is desired the sharpness of the slope is determined b v the position and adjustment of the arm 4S.

Another feature ot' the invention resides in the mechanism for handling the heel and moving it over the cutter. In accordance with the present invention the heel is engaged upon separated points of its tapering side surfaces by the edges of the heel retaining block (it). The downward irri-essuie of this lnflnler tendsy to press the heel firmly against the table 32 and against the member (11. iis is Well undcretoml` and as shown in Fig. 1,-. wooden heels taper outwardljvY troni the bottoni ot the heel to the attaching tace` and the member (il). by engaging merely at sepa rated points the lateral surface Where it tapers ontwardli,v to the attaching face5 acts lo hold the eel firmly in place. Thus1 the construction and operation ot the heel holder is very simple. lit the same time the heel .slides freely over the table in operative relation to the cutter. By this method the heel is concaved without the necessity of having clamping holders operated by cams and I am enabled to provide a mechanism which will take an'v kind ot a heel` even very loiv heels, which are ordinarily very difficult to handle in the ronraving machines know in the art.

l ha ve thus provided in one machine, in adjustable toi-xn, a simple mechanism for accomplishing the following (l) The regulation of the depth ot' the concavity.

'.lhe regulation ot the width oi the roi-.- cavity.

(Il) The regulation ol the taper of the concavity.

(A) The handling of any type ot' heel in the .saine mechanism with slight adjustment or the substitution of minor holdingI parts.

(o) lveans tor lirmly holding theI heel on the l'ront, bach and top and for movingl it bach and forth over the cutter. i

(t3) detachable, readily changeable eutter guard forn'iing a part of the supporting table so as to regulate the degree. o'l' the cutling artion, while at the same time providing a table portion associated With the cutter which will not injure it yet which will properly support the heel beingr passed over it.

The operation ot' the machine is as follows: At the time the operator inserts a heel tho crank 4l extends horizontally to the front, as shown in Fig. 8. This brings the heel holdin;lr mechanism to its extreme forward position. The operator tilts up the elements 59. o() about the pivot 59o. inserts the heel and brings the member (itl down upon its rear surface. thus holding;l the heel dowliward against the table and si-mn'inglr it against sidewise movement relativehY to its holder. The clutch o beim.r thrown. the cam disk i8 and crank 44 begin to rotate. The machine then ;oes through its cycle. the heel holder beine* moved back and forth b v means of the crank Ll-l. and laterallyY at times by the cam disk 18.

rl`he projection l() rotating with the cam member 1S at the end ot a circle oi operations is adapted to throw the clutch lever and the clutch so that the evrle of operations. which imparts to the heel the proper coneavity, will lie terminated and the power disconnected.

The members 59 and (it) are then turned up bv the operator hv means ot a handle 68 and the tinished heel is removed.
